[摘要]在一字形內(nèi)芯防屈曲支撐接觸應(yīng)力研究成果的基礎(chǔ)上,嘗試對十字形內(nèi)芯防屈曲支撐進行有限元模擬分析,研究其內(nèi)芯寬厚比對接觸應(yīng)力的影響和約束間隙對內(nèi)芯屈曲性狀的影響。

Abstract: Based on the research findings about the contact stress of buckling-restrained brace with one-line-shaped core, a tentative finite element analysis of buckling-restrained brace with cross core is conducted to research the width-thickness ratio′s impact on the contact stress and the constraint gap′s impact on the core′s buckling character.
Keywords: buckling-restrained brace; contact stress; cross core
